SPECIFICATION forming part of Letters Patent No. 604,868 dated may ,1898.

; Applidationfiled.OctBberZ lSQVJ To all concern:

Be it knownthat I,- THEODORE H. SCHMITZ,

a citizen of the United States, residing in the city and county'of Philadelphia and State of Pennsylvania; have invented certain'riew'and useful Improvements in Window Structures,

of which the following is a full, clear, and exact description, reference being had to'the accompanying drawings, forming a part of this specification.v

The object of thisinvention is to provide a window structure in which the; sashes may be means whereby access may be readily had to the interior of the sash-weight boxes and to the weights therein and whereby other advantages are secured.

According'to' my invention the windowsashes are'suspended and counterbalanced within the frame, the stiles and guides for the sashes arelbodilyfmovable toward and from the counterweight-boxes, and means are I provided for'locking said stiles and guides in their positions'of adjustment, whereby when the stiles and guides are in their normalposition the sashes are supported in the guides in a manner to be-vertically movable therein, and whereby when the stiles and guides are in their retracted' position the sashes, being unobstructed thereby, may be revolved'within the frame or may be bodily withdrawn from the latter and be" swung orturned exteriorly thereof. Preferably theweighted sash-cords are attached topivoted hangers on the sashes, and the lower portions only of the stiles and guides are adjustable, as stated,the upper portions thereof being stationary, as ordinarily.

In the drawings; Figure 1 is an elevation of my improved window structure, parts being broken away'for 'clearness. Fig. 2 is a verticalsection, as on the line a: a: of Fig. 1, showing one of the sashes as withdrawn bodily an No. 653,816. (No model.)

from the frame and indicating by dotted lines a sash as revolved or inclined in theframe. Fig.- 3 is a transverse section, as on the line y y of Fig. 1. Fig. 4 is a similar section showing'the stiles retracted and indicating by dotted-lines one of the sashes as being removed from the frame. Fig. 5 is a detail of the sash-hanger and adjuncts. Fig. 6 is a perspective of a part of one of the movable stilesections with its lock.v Fig. 7 is a sectional elevation of a portion of a sash, its counterweight, and adjuncts. Fig. 8 is a perspective of sash-hanger hereinafter referred to.

A represents the window-frame, provided with the usual boxes a, in which the sashweights a are contained, and-B'the stiles,pro-

vided with vertical guidewaysb for the window-sashes O 0 *Each of the stiles is preferably constructed in two sections'l 2, each section, with its guides, comprising a single strip provided with parallel longitudinal gro0ves,whereof the intermediate wall serves as the usual parting-strip,while the sidewalls perform the function of ordinary beads to keep thesashes in place.

The upper sections are fixed in position to receive and guide the sashes and are provided with the usual pulleys b for the support and guidance of the sash-cords 0, while the lower sections are fitted in the sides of the window frame to be adjustable toward and from the respective weight-boxes.

In their normal position the lower sections are each in line vertically with the adjacent upper sections, so that the sash-guides of both sections are in alinement to permit the sashes to be slid up and down therein in the usual contained in casings e, which are mortised in the respective ends of each of the lower sections intermediate the gnidcwa-ys thereof. These bolts, by the action of their springs 6 are normally projected beyond the ends of the section, so as to register with appropriate keepers a in the opposing end of the upper section and at the bottom of the windowlrame, respectively. Each of the keepers is provided with suitably-located sockets 6 with the forward one of which the adjacent bolt engages when the stile is in its normal position and with the other socket when the stile is retracted. The bolts are provided with knobs or project-ions c", by means of which they may be retracted from the sockcted keepers.

The sash-cords are connected with pivoted hangers, as I on the sides of the respective sashes, so as to facilitate the revolving or turning of the latter under the conditions stated. These hangers com prise an gle-plates, the vertical members of which are provided with keyhole-slots f, which may be readily and securely applied to headed pins or screws 7" on the sashes, while the horizontal members are perforated to permit the free ends of the sash-cords to be passed therethrough and knotted, as shown. The knots 011 the cords e cover the enlarged portions of the slots in the hangers and thus obviate any liability of accidental disconnection of the parts. To detach the sashes from the cords, it is merely requisite to draw down the knotted ends of the cords and to slip the hangers from the pivot screws or pins on the sashes. (See Fig.

It will be seen that when the sashes are bodily swung from and beyond the windowframe the lower stile-sections may be removed from the frame to permit free access to the interior of the sash-weight boxes and to the weights therein, the walls a of said boxes being appropriately cutaway, as at a Fig. 1, for this purpose. It will also be seen that when the sashes are in place, if the bolts be withdrawn from their keepers, the movable st ile-scctions will press yieldingly against and prevent rattling of the sashes.

As illustrated in Fig. 7, I sometimes arrange at the lower end of the weight-box an additional pulley Z) and pass around the same a cord 0, the extremities of which are attached to the lower end of the weight '10 and to the hanger, respectively, so as to etlect a steady and uniform counter-balancing of the sash. The cord 0 is preferably provided with a spring-section e adjacent to the hanger, so as to maintain the cord taut and insure its engagement with the pulley. In this construction the lower end of the hanger is provided with a slotted lug f, into which is slipped the knotted end of the cord, the action of the spring preventing displacement thereof. .l"re )aratory to removing the sash from the window the lower cords are disengaged from the respective hangers on the sash.

I claim 1. The combination of devices forming a window structure with a main frame,whereby a pair of window-sashes are suspended and counterbalanced within the frame and adapted to be held therein at any angle of inclination or bodily removed therefrom when dcsired; said devices consisting of the following elements in combination, namely, a pair of sectional stiles 15, B provided with longitudinal guideways Z) and composed of two separate and independent sections arranged end to end, the upper section being stationary and the lower section bodily adjustable laterally; springs (Z operating to maintain the lower stile-sections out in normal position to preserve the continuity of the guideways,weightboxes the walls of which are adapted to fur nish one bearing for said springs, locking devices E operating to maintain the lower sections in normal as well as in retracted position, sashes to slide in the guideways, sashcords and counterwcights; said parts being combined, arranged and operating, substan tially as described.

2. In a window structure, the combination with a sliding sash, of a hanger consisting of a vertically-movable portion slotted to engage a pin or stud of the sash, and having at each end a projecting slotted lug, a counterbalanceweight, a cord connected at one end to said weight and at the other end to the upper of said lugs, and a second cord connected at one end to the opposite end of the said weight, and to the lower lug of said hanger, said second cord having a portion of its length constituted by a spring, substantially as specified.

3. In a window structure, the combination with the main frame, of adjustable stile-sections therein, provided with longitudinal guideways, means to maintain the stiles in and out of normal position, sashes to slide in the guideways, and angular hangers F for the sash-cords, pivoted to supports on the sashes, said hangers being constructed with a slotted vertical member, and with opposite horizontal members, perforated for the passage of sash-cords, the knots of which are inclosed in the hangers; and counterweights on the opposite ends of the sash-cords; substantially as described.

a. The combination, forming a window structure, with a main frame, sectional stiles arranged end to end, the upper section being stationary and the lower section being adjustable latcrally, vertical guideways therein for the sashes, weight-boxes having walls of recessed at a? to permit access thereto, springs (Z interposed between the lower stile-sections and the walls of the weight-boxes, and looking devices consisting of normally-proj cctin g spring-actuated bolts c, casings therefor in the ends of the lower section, and keepers e fixed my signature this 28th day of Septemmounted in the opposing end of the upper ber, A.
